The average U.S. visitor spent seven hours, one minute and 41 seconds on Facebook in January, compared with just over two hours each on Google and Yahoo, 25 minutes on Amazon and 16 minutes on Wikipedia.

While Google and Yahoo still have a bigger audience than Facebook, the social-networking site outpaces the competition in how much time its users spend on its pages. Facebook was also the only site listed in Nielsen’s Top 10 to see an increase in time-per-month, growing 9.7% from December.

In June, Nielsen said that the average U.S. user spent four hours and 39 minutes on Facebook per month, which amounted to about nine minutes a day in a 30-day month. In August, that number rose to five hours and 46 minutes, or 11.5 minutes a day.

Facebook, which launched in 2004 initially for Harvard students, has transcended age to become a popular social-networking outlet for many people. Google Buzz, which the search giant unveiled last week, is an attempt to capture some of the increasing time and attention that social sites like Facebook and Twitter are commanding.
